HOW U. SNIVELY, OF KANSAS CITY, MISSOURI.

TRAVELING HUIST.

To all whom it may concern:

Bev it known that I, HOWARD V.

Kansas City, in the county of Jackson and State of Missouri, have invented a certain.

new and useful Improvement in Traveling Hoists, of which the following is a specification.

My invention relates to improvements in traveling hoists.

The object of my invention is to provide a travelin hoist of the overhead type, which is of nove construction, which is strong and durable, which can be easily operated from below and which may be cheaply installed and economically operated.

A further object of my invention is to provide, in a traveling hoist, novel means for manually and automatically controlling the hoisting mechanism.

A further object of my invention is to provide an overhead car with means by which it may be readily attached to or detached from the carriages which support it.

Still another object of my invention is to provide novel means for driving the hoisting drum carried by the car, and which will hold the drum from being turned by the weight of the load, when the driving means is operatively disconnected from the motor.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which preferred embodiment of my invention,

Figure 1 is a side elevation, partly broken away, of my improved traveling hoist.

Fig. 2 is a plan view of the car and mechanism supported thereby, the supporting hooks being shown in cross section.

Fig. 3 is a vertical sectional view on the line'33 of Fig. 1. v

Fig. 4 is an end elevation of the car and supporting means, the I beam being shown in cross section.

Fig. 5 is'an end elevation of the bucket and parts connected therewith, a portion of the drum and car being shown in vertical I Specification of Letters Patent.

Application filed July 12, 1915.

SNIVELY, a citizen of the United States, residing at .supported on an angle plate 26, cured to the beam 6 at the side opposite to Patented May 21,

1918. Serial No. 89,458.

comprising a substantially horizontal I beam upon the two lower flanges of which are adapted to run supporting wheels 2 with which each of two carriages 3 are provided.

Each carriage 3 has mounted in it below the I beam 1 a transverse bolt 4 which supports a link 5.

The car is provided with a base consisting of a horizontal channel beam 6, the flanges of which extend downwardly and have respectively secured to them arms 7 of two upwardly extending hooks 8 which are respectively adapted to be releasably attached to and supported by the link 5, Fig. 3, and Fig. 4.

Mounted on the channel beam 6 is a motor 9 of any suitable type, the one shown bein a gasolene engine provided with a cran shaft 10 disposed horizontally and transversely of the car and having rigidly secured thereto two pulleys 11 and 12, Fig. 2.

Rotatably mounted in the bearings 13 supported by the beam 6 is a hoisting drum 14, the axis of which is disposed horizontally and longitudinally. To one end of the drum 14 is secured a worm wheel 15 which engages a worm l6'provided on a horizontal transverse rotary worm shaft 17 which is mounted in a bearing 18 supported on the beam 6 and in a bearing 19 supported on a longitudinal angle bar 20 which is secured to one of the flanges, at the outer side thereof, of the channel beam 6.

Secured to the worm shaft 17, Figs. 1 and 2, is a pulley 21 which is connected by a belt 22 with a pulley 23 which is rigidly secured to a horizontal transverse driving shaft 24, which is rotatably mounted in a bearing 25 which is sethat to which is secured the angle bar 20.

The driving shaft 24 is also rotatably mounted in a bearing 27 supported on the angle bar 20, Fig. 4.

Freely rotatable on the driving shaft 24 are two constantly "driven pulleys 28 and 29. A crossed belt 30 connects the pulleys 11 and 28, and a straight belt 31 connects the pulleys 12 and 29. The crank shaft of the engine 9 will, therefore rotate the pulleys 28 and 29 in opposite directions.

In order that the shaft 24 may drive the drum 14 so as to wind thereon a cable 32 attached to the eri hery of the drum, there is secured to tile s aft 24 a clutch member 33 provided with the usual two pivoted arms 29 and be driven thereby,

. are adapted to engage the pulley 28 so as i Fig. 4, the lower to be driven thereby, thus driving the driving shaft 24 in-the same direction as the pulley 28.

For alternately swinging the arms 34 and 36, there is slidably splined to the shaft 24 a double cone member 37, having one rounded end adapted to engageand swing the arms 34, and having the other rounded end adapted to engage and swing the arms 36. In Fig. 2 the cone member 37 is shown in the neutral position disengagedgfrom"both sets of arms 34 and 36. At such time the shaft 24 will not run.

For longitudinally sliding the cone member 37 on the shaft 24, to and from the neutral position, said cone member is provided with a central annular peripheral groove 38, I

in which extend two inwardly. extending diametrically opposite projections 39, provided at the upper end of a vertical lever 40, end of which is provided with two arms 41 and 42, which extend transversely in opposite directions from a longitudinal pivot bolt 43, which supports the lever 40 which is mounted in an angle plate 44 secured to the upper side of the channel beam 6. p

Attached respectively to the arms 41 and 42, are two ropes 45.and 46 which extend downwardly respectively through two vertical holes 47 and 48 provided in the channel beam 6. b An operator on the groundbelow rgpes 45 and 46 will, through the intermediacy of the cone member 37 and clutch arms 34 and. 36, effect a driving connection bethe car tween the shaft 24 and pulleys 29 and 28,-

so as to alternately rotate the drum 14 so as to wind thereupon and to unwind therefrom the cable 32. 3

When the lever 40 is swung so as to depress the arm 42- from the neutral position shown in Fig. 4, the pulley 28 will be driven so as to cause the drum 14 to rotate in a direction such that the cable 32 will be unwound therefrom. Upon depressing the arm 41 the pulley 29 will be driven, and the drum 14 will be rotated so as to wind thereon the cable 32. p

The lower end of the cable 32 is attached to a transverse bar 49, Fig. 6, opposite ends of which are connected by two pairs of pair being respectively. secured to the adjaalternately pulling downwardly on the a transverse bolt 52, the levers of each cent ends of two scoop members 53, which form the two halves of a clam shell bucket.

The levers 51 are crossed and their upper ends attached to the chains 50, so that the upward pull on said cable by the drum 14 and the load carried in the scoop members 53 tend to keep said scoop members in the closed position shown in Fig. 5.

In order that the bucket may be automatically dumped after it has been raised and transported to the desired place, two pairs of chains 54 are attached respectively to the outer edges of the scoop,members 53. Said chains 54 at their upper endsare attached to the lower end of a chain 55, the upper end of which is attached to a long link 56,

which is provided with a longitudinal row of holes 57, Fig. 6, three being shown in the drawing, which are adapted to receive a hook 58 which is secured to one of the flanges of the channel beam 6, Figs. 5 and 6.

When the bucket has been loaded and elevated by the cable 32, and has been transported to the place where it is to be dumped, the operator at that place pulls downwardly on the rope 46, thus engaging the core member 37 with the clutch arms 36, thereby driving the shaft 24from the pulley 28, and thus, through the mechanism already described, rotating the drum 14 so as to unwind the cable 32. As the cable 32' unwinds from the drum, when the bucket reaches the pre-determined dumping position, the weight of the load will be transferred from the cable 32 to the chains 54 and 55, the operator having previously engaged the link 56 with the hook 58. As the cable 32 continues to lower, the chains 54 will swing the scoop bucket reaches the desired height, in case 1 that the operator fails to operate the lever 40 by pulling it by means of the rope 46 to the neutral position shown in Fig. 4, a lever 59, Figs. 1, 2 and 4, is pivoted by means of a bolt 60 between two angle plates 61 which are secured to the under 'side of the channel beam 6, said lever 59 extends under the drum 14 and isprovided, with alongitudinal slot 62 through which the cable 32 is adapted to travel.

The opposite end of the lever 59' extends I over and-is adapted to engage the upper side of and depressvthe arm 42 of the'lever 40, Figs. 2 and 4.

When the bucket rises to the proper height, at which it is to be transported, the beam 49 will engage the lever 59 and will swin upwardly the end of the lever having the s 0t 62, thereby depressing the opposite end of the lever and the arm 42 to the neutral position shown in Fig. 4. The cone 37 will thus be disengaged from the clutch arms 34 and the pulley 29 will no longer rotate the driving shaft 24. The drum 14 will thus stop running and the winding thereon of the cable 32 will cease. By

grasping both ropes 45 and 46, and pulling in the direction the car is intended to travel, the car may be caused to travel along the track beam 1, which after leaving the place of loading maybe inclined so that the car will run to the dumping place by gravity, if desired.

In operating my invention, the car is drawn to the loading place, after which the operator below pulls downwardly on the rope 46, thus engaging the clutch arms 36 with the pulley 28, thereby rotating the driving shaft 24 so that the drum 14 will unwind the cable 32, thus lowering the bucket to the loading position.

After the bucket is loaded, the operator, who in the meantime has pulled the rope 45 so as to slide the cone member 37 to the neutral position and thereby stopping the drum 14, now pulls the rope 45 so as to engage the clutch arms 34 with the pulley 29.

. ,The drum 14 will now be rotated so as to wind thereon the cable 32, thus elevating the bucket to the transporting position, at which time the lever 40 may be operated either automatically by the lever 59 or manually operable from below for-oscillatthrow the cone member 37 to the neutral position. The car is then run to the dumping place and the load discharged in the manner already described.

What I claim is 1.111 a traveling hoist, a hoisting drum, means including clutch mechanism for re tating said drum, a cable secured to the drum and adapted to be wound thereupon, a lever having means for actuating said clutch mechanism a second lever adapted to engage the first lever so as to actuate the clutch mechanism to stop the drum, means manuall operable from below for oscillating the rst named lever, and means secured to said cable for swinging the second lever into operative engagement with the first lever.

2. In a traveling hoist, a hoisting drum means including clutch mechanism for rotating said drum, a cable secured to and adapted to be wound on the drum, a lever having means for actuating said clutch mechanism and provided with two arms exmembers constantly rotatable in opposite directions, a clutch mechanism in driving engagement with the driving shaft and movable from a neutral position into driving engagement with either of said driving members, manually operated means for forcing the clutch mechanism to and from the neutral position and into and out of driving connection with said driving members, an operating device carried by the cable, and means operable by said device for shifting said manually operated means to the neutral position.'

4. In a'hoist, a hoisting drum, a cable attached thereto and adapted to be wound thereon, a rotary driving shaft, two driving members constantly rotatable in opposite directions, a clutch mechanism in driving engagement with the driving shaft, and mova le from a neutral position into driving engagement with either of said driving members, a manually operated lever for forcing the clutch mechanism to and from the neutral position and into and out of driving connection with said drivingmembers, an operating device carried by the cable, and a lever adapted to be engaged and swung by said device and so connectedwith the first named lever as to swing the. latter to the neutral position when the second named lever has been moved by said device to a pre-determined position.

In testimony whereof I have signed my name to this specification.

HOWARD V. SNIVELY.
